Question about Vizio SV420XV 42 in. LCD TV

2 Answers

Frame periodically freezes on Vizio 37'' TV

This TV is hooked up to an antenna with a booster. In the last week, it has frozen two times. The first time it was 1 1/2 hrs. later that I returned into the room and saw it frozen on the news station at 8:29 AM My 42" Vizio has frozen twice in the first two weeks we've owned it. I don't think reception or signal quality is the problem, as it's hooked to cable TV. djchillsync's solution doesn't apply.

Digital tv (or DTV) off the air is different from the old analog type tv signal. Both use basically the same type antenna, I use UHF on my dtv and that works. It used to be if the signal was weak you got a snowy picture, mostly white and black speckles. With digital tv signal there is no snow, the picture instead freezes and the motion of the tv picture stops (pixels may get mixed up too), it can't read what is next in the video so it stops to figure it out. When it gets a better signal it works, but you may have to redo the basic search for stations for the automatic configuration to get the best picture for the station to work good. A digital TV has a search function from the remote, dtv converter box has it too.

Your statement is confusing. Why? because you stated " This tv is hooked up to an Antenna with a Booster", then you said it's connected to Cable Tv. I will answer this both ways for you.
If your on an Outside Antenna or Rabbit Ears, even with a booster, if the signal is not good prior to getting to the antenna then a booster only amplifies what it see's and that may be as we call it, "garbage". In a HDTV the freezing can happen when that situation is at hand, however if you are on Cable and we know the signal is clean ( we hope? ) then the problem is with the software in the set and should be looked at by a service center, or if it's right out of the box then I would exchange it.
In digital technology there's no maybe, it's yes or no! If the signal is not what's required, then you get what your experiencing now, IF, there's nothing wrong with the set, and there may be. I just repaired another brand doing the same thing and it was the Main Control Module. So, I hope I helped you in isolating the problem. Please keep me posted...

Vizio e550i-b2 no picture but has back light, power light comes on and fades off, wondering what board is bad?


In most cases, its T'Con board. This type of fault can occur due to a faulty main digital board too. Your TV need a through check up. Contact any service technician. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

I have a Vizio model E320Vl TV. after working for about two hours it shuts off. You can unplug it and wait about 10 minutes and it turns back on but will shut off again after awhile.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
